Hermitian fft
http://wwwuser.gwdg.de/~jjahnel/Arbeiten/manin7a.pdf WitrynaIf you use the standard Hermitian transpose instead, ', you'll get a scrambled result. In summary, given a square matrix variable X, you can perform a 2D FFT on a square CVX variable as follows: W=fft(eye(size(X)); W*X*W.' Again, note that I am using a non-conjugated transpose above. Please note that 2D DFTs get big fast.
